Namely, in Fig. 4, the lubricant oil 14 that accumulates in the lubricating oil tank 13 is picked up by oil pump 17 from the not shown oil-feed port that is located on the lubricant oil case lid 13a, from the spray spout 10 of the spray spout 9 of 1-2 level small gear 7 usefulness and 3 grades of small gear 8 usefulness towards input gear 6,1-2 level small gear 7 and 3 grades of small gears 8 spray, be used for the lubricated of these speed increasers 4, cooling, even but rebounded from lubricated pasta 14b by the lubricant oil 14a that flies with the input gear 6 of the speed increaser 4 of High Rotation Speed and 3 grades of small gear 8 bullets, do not reach speed increaser 4 yet, can eliminate the mechanical loss of bringing because of rebounding of lubricant oil 14a.Here, reference character 24 is sense of rotation of input gear 6.
In addition, the turbocompressor of relevant embodiments of the present invention as shown in Figure 5, the interstage cooler of the anti-motor M side of the 1st grade and the 2nd grade of interstage cooler axis C1, C2 direction cover be respectively equipped with the 1st and the 2nd interstage cooler 11,12 water supply coordinate mouthfuls 31,31 and draining coordinate mouthfuls 32,32, so above-mentioned turbocompressor arranged in many situation, coordinate to supplying water mouthfuls 31 and draining coordinate mouthful 32 water supply piping 31a that connect and drainage piping 32a can both be not crooked and connect with respect to supply water main pipe arrangement 31b and draining master pipe arrangement 32b.
Namely, water supply piping 31a and drainage piping 32a are after generally perpendicularly extending from supply water main pipe arrangement 31b and draining master pipe arrangement 32b, not crooked, and to be configured in this water supply piping 31a and drainage piping 32a roughly coaxial water supply coordinate mouthfuls 31 and draining coordinate mouthfuls 32 and be connected.Therefore, the pipe arrangement construction is simpler, can also reduce to arrange the space, and these pipe arrangements can not become the obstacle of the maintenance of compressor.
And then turbocompressor such as Fig. 2, shown in Figure 4 of relevant embodiments of the present invention in lubricating oil tank 13, are provided with the isolating plate 16 that the oily reservoir 15 in this case 13 is divided up and down.In addition, form the aperture portion 16a that will be communicated with by the oily reservoir up and down 15 that isolating plate 16 is divided by the end of this isolating plate 16 and the inwall of case 13.
The lubricant oil 14 that is flown by speed increaser 4 bullets and accumulate in the oily reservoir 15 is picked up by oil pump 17 from the not shown oil-feed port that is located on the lubricant oil case lid 13a, again for input gear 6,1-2 level small gear 7 and 3 grades of small gears 8, also have lubricated, the cooling of not shown bearing, but by the lubricant oil 14a that said gear 6~8 bullets with High Rotation Speed fly air (bubble) is involved in and gets back in the oily reservoir 15 in the lubricating oil tank 13.The lubricant oil 14 that contains the state of this bubble becomes the decline of the ability of said gear 6~8 and bearing lubrication, cooling and the reason of corrosion.
As the method that bubble is eliminated, generally be the volume that increases lubricating oil tank 13, make the time of returning till the lubricant oil 16 that comes is reused elongated, bubble floating is played on the pasta and the method for dispersing, but need so a large amount of lubricant oil 14.By isolating plate 16 is set as described above, till being inhaled in the oil pump 17 to lubricant oil 14, flown by said gear 6~8 bullets and drop to lubricant oil 14 on the lubricated pasta 14b of oily reservoir 15 along the flowing of lubricant oil 14 of the oily reservoir 15 that is isolated the upside that plate 16 divides and via aperture portion 16a, then along the flowing of lubricant oil 14 of the oily reservoir 15 that is isolated the downside that plate 16 divides and towards lubricant oil case lid 13a direction.
Therefore, advance along long path reliably till being inhaled in the oil pump 17 to lubricant oil 14, the time till recycling is elongated, and the bubble floating in the lubricant oil 14 plays on the pasta, so bubble is dispersed to the gas phase sections in the speed increaser housing 5.
In the situation that does not have isolating plate 16, drop to from speed increaser 4 lubricant oil 14 on the lubricated pasta 14b of lubricating oil tank 13 with shortest path towards lubricant oil case lid 13a, and compare with it, in the situation of the embodiments of the present invention that are provided with isolating plate 16, the above-mentioned lubricant oil 14 that drops on the lubricated pasta 14b of lubricating oil tank 13 is gone out in the lubricating oil tank 13 via the distance of about 3 double-lengths.
As described above, according to the turbocompressor of relevant embodiments of the present invention, can make as the bubble collapse in the lubricant oil 14 that lubricates the decrease reason that reaches cooling capacity of speed increaser 4 and bearing.And then, can reduce the use amount of lubricant oil 14, the volume that can make lubricating oil tank 13 is small amount also, so produce the also advantage of miniaturization of size that can make compressor integral body.
